摘要
汽車轉向系統(tǒng)可按轉向的能源不同分為機械轉向系統(tǒng)和動力轉向系統(tǒng)兩類。
汽車電動助力轉向系統(tǒng)是一種新型的汽車動力轉向系統(tǒng)，與傳統(tǒng)液壓轉向系統(tǒng)相比，采用電動機直接提供助力，具有多方面優(yōu)越性。近年來已有很多中高檔汽車配備了動力轉向系統(tǒng)裝置，EPS研究也成為汽車工業(yè)的熱門課題之一，具有重要研究價值和巨大潛在應用前景。
在本文中重點進行齒輪齒條轉向器的設計計算和對轉向齒輪軸的校核，及轉向傳動機構的優(yōu)化設計。主要方法和理論采用汽車設計的經驗參數(shù)和大學所學機械設計的課程內容進行設計，并做了歸納和總結。
關鍵詞 轉向系統(tǒng)；電動助力轉向系統(tǒng)；齒輪齒條轉向器；優(yōu)化設計

Abstract
The steering system can be divided into mechanical energy and power steering system.
Electric power steering system is a new type of vehicle power steering system, compared with traditional hydraulic steering systems, directly with the motor power, has many advantages. In recent years, many in the luxury car have been equipped with a power steering system device, EPS studies have become a hot topic in automotive industry, great research value and great potential applications.
This article focus on the design of the rack and pinion steering gear shaft calculation and verification, and optimization of steering linkage. The main methods and theories of experience with automotive design parameters and the university curriculum in mechanical design to design, and made and summarized.
Key words Steering System；Electric Power Steering ；
